FIRE FGT.

Application filed March 29, 1922.

' To all trimm t may concern Be. it known that Juntos B. lonHLnn, a citizen ofthe United States, and residing at cincinnati, in the county of Hamilton and State of Ohiom have invented a new and useful improvement in Fire Pots, of which the following' specitication is fuli disclosure.

This invention relates to improvements in iire-pots, and linings therefor.

Objects of the invention are to provide an improved tire-pot and sectional or seg;- mental. iininp' therefor composed of a piulrty of segments or elements, each of which capable of locking' engagement with the not, and each of which when positioned as lining therefor conforms to the contigu- 1ation ot the inner surface of the pot, all lements when assembled together, forming r continuous protect-ive wall of even thickness, locked within the pot,and all elements being introducible in directions at .right angles to the inner surface of said pot,

JAnother object is Vto provide a single means in the form ot a key-piece or segment for locking all segments of the lining, after assembly. against either circumferential, or dianietric or radial displacement or removal, said key-piece being also introducible in a direction at a right angle to the side of the pot.

Other objects and certain advantages will be disclosed in the description ot the drawings forming a part of the specification and in said drawings:

Figure 'l is a plan View of my improved lire-pot showing the refractory lining therein. portions of the upper web of the pot being` broken away to clearly show, in addition to the general arrangement of the segments, the manner of locking the same by the introduction of a key-piece or locking' segment.

Figure 2 is a detailed perspective of one of the fire brick elements, or segments.

Figure 3 is a diametric vertical section on line 3-3, Fig. l.

Figure et is a fragmentary section on line 4 4, Fig. 1, illustrating the manner `of introducing` the segments within the lockinnr grooves of the pot.

The pot l is, in this instance, of inverted frustrum-conical configuration, although pots of cylindrical conguration are contemplated, and provides upper and lower internal, horizontally disposed, circumfer- Serial No. 547,826.

ential webs, respectively 2 and 3, the lower web 8 having an upstandinp,I peripheral rib `orjtlangge 5, forming with said web and the wall of the pot, an upwardly facing` channel or groove 6, said groove and flange foi-ming` a means for pocketing and locking' the lower end of the segments or elements of the linpj, more fully described hereafter. The upper web also provides circumferential downwardly directed or rib 7 of greater depth than its companion bottom flange, said rib F forming with the web and wall of the lire boil, a downwardly facing" channel or Igroove S, of substantially greater depth than the lower (groove. The refractory lining; of the pot is composed of a pluraiity of segments or sections 9, the top and bottom ends of which are designed to engage within the grooves 8 and t3, and the said sections are of even Tall thickness ande when assembled, their inner faces lie flush with one another and with the inner alincd sur faces of the flanges 7 and 5. Each segment or sect-ion 9 is of less height or length than the distance between the bottom of grooves and each is provided at its lower inner edge with an angular circumferential notch. 10, and at its upper inner edle with a similar circumferential angular notch ll. of greater vertical depth than. the notch l0.

As shown in Figure fl?, each segment or section is introduced by first inserting 'the upper end of the section into the deeper groove 7 to raise the lower end of the segment. su'tiicientlv to clear the rib 5, and subsequently swingine` the segment inwardly and against the side of the pot and allowing the section to drop into the lower groove 6, after which the sections or segments assume the position shown in Fig. 3. with the lower end locked in channel 6, and the upper end extending; partly into the groove 7, and also locked, thus preventing any possibility of the brick being disengaged from its grooves by tilting' inwardly. The sec-- tions are thus successively introduced into the grooves until all but the key segment 12 have been assembled, after which the locking` or key section l2 is introduced as shown in Figure l. The section 12 .is similar to the other sections of the lining except in respect to its side faces 13 which are parallel to one another instead ot radial or flared as in the case of the other sections.

It Will be noted by inspection of Fig, l

Y relatively the reason that the sides 13 are parallel, (as

indicated by lines a, in Fig. l) with respect to the radially related sides of the segments 9 at each side thereof.

Having described my invention, l claim:

l. A frustunrconica-l `tire-pot, formed with upper and lower horizontally disposed annular webs having respective downwardly and upwardly directedperipheral flanges, delining' with the wall of said pot respectively, deep and shallow opposine'ly faced grooves, and a lining' toi' said pot comprisingltapering` circular sega ents, each havin@ upper and lor-:er interior peripheral angular end notclies,:said notches and ends en- Vgageable with 'said vflanges and grooves for locking' said segments within said pot.

2. A frustum conical lire-pot, termed with upper and lower horizontally disposed webs heaving` respective downwardly and upwardly directed flanges defining with the walls of said pot respectively relatively deep and shallow opposingly Ylaced grooves, a lining' `lor said pot comprisinc tapering' segments, said segments providing' upper and lower in terior peripherallangnlar end notches, said notches and ends engageable Vwith said flanges and grooves lor locking said. seg ments therein.

5l'. A, frustum conical lire-pot, providing,y upper and lower horizontal webs, havingl opposingrly related circular Q;rooves therein,the upper or greater depth than the lower, a refractory lining' for said pot comprising' circular segments of refractory material of isosceles trapezoidall configuration, havingr sides radial with respect to the central axis of said pot and providing` upper and lower peripheral angular'locking` notches, said segtheir plane end surfaces radially related toV the central vertical axis of said pot, and providing upper and lower peripheral angular notches eilgjaneable withv said 'flanges' for locking` sa l seements therein, the height of said Vsegments beine' less than the distance letrreen the bottoms of said' opposingfly related grooves.

5. hollow rustum-conical lire-pot, providing' upper and lower horizontal webs, having' opposinejly related circular channels therein, the upper of greater depth than the lower, a refractory lining` for said pot coniprisinp' a plurality of circular segments ot refractory material ol isosceles trapezoidal configuration.. hz'ivingr plane end 'faces radial with respectto the central axisoi said pot'and i'froridingl upper and lower peripheral angular locking' notches, said segments designed to he siuzccssively introduced and locked in said grooves, and a key segment, having' parallel plane end tacos, allowing' for its radial introduction as a lieylpiece ii'or locking all sen'nicnts against circnml'erential and radial displacement.

ln witness whereof, l hereunto subscribe my naine, as attested by the two subscribing witnesses.
